Problems solved by technology

Oxidation layers must be removed in a laborious manner by sanding off, since the oxide layers can mostly only be painted imperfectly
Furthermore, it is problematic that the zinc coating is lost in the area of ​​the cutting edge in the case of already galvanized workpieces, so that regalvanizing is required
[0005] In principle, the reprocessing of the cutting edges is very costly in terms of time and labor, since the reprocessing of the cutting edges is often also carried out manually
Furthermore, reprocessing is cost-intensive, so that the manufacture of workpiece parts is undesirably prolonged and cost-intensive

Embodiment Construction

[0067] look first figure 1 , in which a beam processing device known per se for beam cutting of plate-shaped workpieces is visualized. The beam processing device designated generally by the reference number 1 comprises a beam cutting device 2 with a beam head 3 and a table 4 with a planar workpiece support 5 for a workpiece 9, for example a stack of flat sheet metals. )(exist figure 1 not shown, see Figures 2 to 6 ). The workpiece carrier 5 is spanned by a crossbeam 6 which is guided displaceably in a first axial direction (x-direction).

[0068] Mounted on the cross beam 6 is a guide carriage 7 for the beam head 3 which is displaceably guided on the cross beam 6 in a second axial direction (y-direction) perpendicular to the first axial direction. The beam head 3 can thus be moved parallel and relative to, for example, a horizontal workpiece holder 5 in a plane extending through the two axis directions (x, y directions). Furthermore, the beam head 3 is designed to be dis...

Abstract

The invention relates to a method for the beam machining of a workpiece (9) from which at least one workpiece part (26) is intended to be severed, using a focused machining beam (14), which comprises the following steps of: - creating a hollow (17) in the workpiece (9) using the focused machining beam (14), wherein the hollow (17) is created along at least one portion of a contour (27) of the at least one workpiece part (26) to be severed from the workpiece, - altering a focal position of the machining beam (14) such that the machining beam (14) has a smaller beam diameter on the workpiece (9), - creating a gap (18) in the workpiece (9) using the machining beam (14) with the altered focal position along at least one portion of the contour (27) of the at least one workpiece part (26) to be severed from the workpiece (9), wherein the gap (18) is created at least partially within the hollow (17).

Description

technical field [0001] The invention is based on the technical field of beam machining of metal workpieces by means of a focused machining beam. Background technique [0002] Laser cutting devices available on the market enable the automated production of workpiece parts in large quantities and with high precision. Here, workpiece parts are cut out of the metal workpiece by means of a laser beam. Advantageously, holes can also be introduced into the workpiece part to be cut out by means of a laser. [0003] Depending on the type of laser cutting method used, the cutting edges produced by the laser require complex mechanical reprocessing in each case. For example, the cutting edges must be rounded or prepared for subsequent processing by smoothing or roughening. This applies in particular to the cutting edge of a hole in an already cut workpiece part, which is usually provided with a chamfer (sink) if the hole is to be used for fastening the workpiece part, for example by ...
